I've got a 6 year old female that I've recently purchased who has never eaten anything but live mice. 1 adult per week, despite her size. :-( I'm wanting to switch her to frozen rats like my others are eating, but don't know which direction to work on first...

A little history... I've attempted to feed her for 5 weeks now, every 7 days. The first 4 I tried rats. She refused 2 frozen and 2 live. Last week I got her a live adult mouse as well as a live small rat. She ignored the rat for 10+ minutes (under observation) but pounded the mouse within seconds...

so which would you switch first? To rats, or to frozen?
